Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 07-20-aia AIA The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 07-23-aia AIA The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. 07-21-aia AIA Claim (s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sun et al., in view of Zewail et al. (US 2022/0007421) Regarding claim 18, Sun fails to disclose obtain an indication of a second subset of random access occasions of the plurality of random access occasions for the first SSB. However in a similar field of endeavor, Zewail discloses obtain an indication of a second subset of random access occasions of the plurality of random access occasions for the first SSB ( The base station 110 may determine the SSB-to-RACH occasion mapping information for the RACH procedure by mapping RACH occasions included in the first set of RACH occasions to one or more SSBs and by mapping RACH occasions included in the second set of RACH occasions to one or more SSBs … the one or more SSBs mapped to the first set of RACH occasions may be the same one or more SSBs mapped to the second set of RACH occasions, [0094]-[0097] and [0099] and [0127]-[0128] and [0150]) . It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains to incorporate the concept of obtaining/determining an indication of a second subset of random access occasions associated with a SSB as disclosed by Zewail into the method for configuring random access parameters comprising an indication of which SSB(s) are associated with the triggered random access occasions as disclosed by Sun in order to improve the system and flexible determine random access parameters, such as a second set of RACH occasions, so that UE may flexibly utilize RACH occasions for different purposes . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim 3, 4, 13, 14 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. He (US 2023/0403689) disclosing a terminal device determining a first random access occasion set; and the terminal device determining an association relationship between the first random access occasion set and a synchronization signal block (SSB)(abstract). Zhou et al. (US 2021/0029738) disclosing base station 105- b may configure a mapping of a set of SSBs to the subset of allowed random access occasions and a subset of forbidden SSBs (correlating to a second subset of random access occasions)…The set of SSBs may also indicate a mapping of the set of SSBs to the subset of the allowed RACH occasions and a subset of forbidden RACH occasions of the set of RACH occasions and Base station 105- b may identify, from the set of random access occasions indicated by the random access channel configuration, a subset of forbidden random access occasions in accordance with the forbidden mask, where the subset of allowed random access occasions is different from the subset of forbidden random access occasions ([0141]-[0142] and [0166]-[0167] and [0178] and [01822] and [0012]). Abedini et al. (US 2023/0029663) disclosing network node 705 may receive a first SSB bitmap to identify which SSBs are associated with FD ROs and a second SSB bitmap to identify which SSBs are associated with HD Ros ([0094]).
